Probable cause & findings

The pilot's failure to maintain a proper approach path, which resulted in impact with trees.

Factual narrative

During the final approach for landing, the airplane was too low and struck trees short of the runway threshold, spun about 180° then impacted the ground. The airplane sustained substantial damage to the left wing and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot failed to submit the NTSB Form 6120.1 Pilot/ Operator Aircraft Accident/ Incident Report.
